FLOOD-GATE.

SPECIFICATION forming part of Letters Patent No. 290,265, dated December 18. 1883.

Application iled July 13, 1888.

To all whom, it may concern:

Be it known that I, EMMET P. PorNDnX'rnn, a citizen of the United States, residing at Woburn, in the county of Bond and State of Illinois, have invented a new and useful Flood- Gate, of which the following is a specilication, reference being had to the accompanying drawings.

This invention relates to flood-gates adapted to be built across brooks, creeks, and lsimilar water-courses, as well as across ditches which are for the most part dry; and it has for its object to provide means whereby the gate will be opened to admit of the rush of water during a' freshet and closed as the iiood subsides. This invention also provides a passway for stock, or otherwise, at the pleasure of those who shall erect the gates.

To attain the aforesaid objects, my invention consists in certain details of construction and combination of parts, as hereinafter fully set forth, and particularly 'pointed out in the claims.

In the accompanying drawings, Figure l is a perspective view of my improved gate; and

Fig. 2 is a crosssection of the sa ea portion being broken away to show the latch?.

The same letters refer to eorrespdnding parts in both gures. l,

Referring to the drawings, A designates the base of my improved gate, said base being made from heavy timber, and having erected thereon at each end standards Bl, x.,ihe inner face of the standards has planks C secured to the same, and in the lower end of said planks the gate D is journaled. Said gate consists of a horizontal bar, cZ, curved on its under side, and having fingers or rods cl projecting outwardly therefrom, said gate being formed of two parts connected by a plate, e', and one or more rods, e2, a staple or gudgeon, f, being passed over one of the rods, and then secured to a block, f', attached to the base A. The object of forming the gate in sections is obvious. The base A is made ofv such size as to accommodate the stream over which the gate is to be built, and the standards are erected thereon correspondingly. By adding one or more sections to or taking one crmore sections therefrom, the gate can bcyadiusted to the size of the stream. The onterf elitist, of the gate are provided with extended fingers or (No model.)

I bars E, arranged to fit flat against a triangular frame, F, secured to the standards B. To the sides of bars E are attached cords G, which pass over pulleys H, jonrnaled on the outside of said standards, and have a weight, I, depending therefrom. 'Ihe latter, while it offers sufficient resistance tending to keep the gate closed during an ordinary flowof water, will be overcome by a flood and permit the gate to swing outward, as shown. A curved lever, J, is connected directly to thebars E, and by a pivot-plate, K, to the standards B, said lever and plate being used instead of the cord and pulley to raise and lower the gate. will be obvious that these devices can be used in conj unction-that is, the weighted cord and pulleys may be connected to the gate so as to automatically raise the same, while the curved lever and pivot-plate may also be attached to the gate so as to either lower or raise the same.

L designates a pivoted latch formed of two parts or arms, Z Z, fitted within a recess, m, of the standards B. One of the arms, Z, is formed with a hook, n, adapted to catch over the upper end of bars E, and provided with a shoulder, n', abutting against the upper corner or shoulder, b, of the standard. Each arm of the latch is pivoted and formed with extended curved ngers o, the finger of part Z overlapping the adjacent finger. To the outer end of arm or part Z is attached by screw-eyes p a rod, M, having a float, N, connected to the lower end thereof, said rod sliding througha ring secured to the standards, and fitting partly within a depression in the face of said standards. It will be seen that as the depth of water increases the fioats N will be raised, since they are lighter than the water, and as the iioats rise they elevate the arms or parts Z of the latch by means of the connecting-rod M. The elevation of arm Z causes its finger o to bear onthe corresponding finger of arm Z, thereby elevating the latter and freeing the bars E, attached on the ends of the gate, from under the hook a, thus allowing the gate to drop.

The operation of my invention is obvious. As the fiow of water increases in depth the float N will be raised, thereby disengaging the,` latch from bars E of the gate, permitting said gate toswing outward by the pressure of water thereon. As the iiow of water decreases the=` gate will be allowed to swing back against the standards, so as to close the same, the gate being held in place by the pivoted latch hocking over the end bars, E. Thus the gate will be opened to admit ol" the rush of water during a freshet, and will he closed as the water subsides.

The planks C extend up along` the entire inner face of the standards, so as to protect the latches from the action oi' the 1lood,wliile the base A may he dispensed with and the standards be secured directly to the ground.

In constructing` my gate I use any suitable materials-such. as iron and woodand l'or this reason I do not state the materials to be used, but leave it to the will oi' thc maker.

Having described my invention, I claim- 1. A Hood-grate provided with end bars, in combination with latches pivoized in slandards I3, said latches heilig; formed ol' two arms, One of which is provided with a rod, M', and a iloat, N, :is and l'or jihe pnrpoie sei,- lorlh.

2. A 'Ilood gate provided with mi liars, in eon'ibinaiion with latches pivoted in standards I3, said latches beingr formed ol two arms having overlappingv iingers o, one ci" said arms being provided with a rod. BI, and iioat IQ, as and for the purpose set forth.

3. In a flood-gate, the gate i), provided with end bars, E, in combination with standards o B )lanks C. frame F pivoted latches L, rod 3 7 l 7 M, 'float N, cord G, Weight I, pulley II, and lever J, as and for the purpose set forth.

4L. In a flood-gate, the gate D, provided with end hars, C, in combination with standards I3, pivoted latches L, rod M, iloat N, cord or rope G, weight I, pulley II, lever .T, and plate K, as and for the purpose set forth.

5. A flood `gate provided with extended end bars, I'l, at each end, in combination with standards B, latches pivoted in recesses therein and hooking` over the end bars of the gate, a lloat eonnecting with the latches, a pulley, II, jonrnalrij inthe standards, and aweighted cord or rope attached to the end hars, E, and passing,l` over the pulley, as and for the purpose set forth.

o'. A ioodgate provided with end bars, in combination with l-.itches connecting with said end hars, und formed of two pivoted arms, a ilont connecting; with one of said arms. and a '11ml wird or rope atiaehed to the end r ci' ih@ gate, as and i'or the purpose set forth.

in 'testi mony thatI claim the foregoing as my own I have hereto :rl'lixed my signature in presence of two witnesses.
